Woodman Components' Capsule PH is a specially-designed expander plug and top cap assembly for oversize 1.5" steerer tubes. The simple wedge-and-collar design works well and is easily serviced. Additionally, the Capsule PH supports the steerer tube's interior structure from the clamping forces applied by the stem. This design makes this expander ideal for carbon fiber steerer tubes, but it works equally well with aluminum steerers.
